I was so excited when I found these on the web site. Price was phenomenal, delivery was FREE (this is a big deal as I live in remote Wyoming), the specifications were great and they were in stock..... so why am I giving these only three stars?... 1-They have a really dumb design that makes them horrible to build with one person and almost reasonable to build with two people. It would have cost maybe a buck per unit to fix the dumb design. 2- I have 40 to 175 lbs per shelve. The units are rated at 600 lbs per shelf and 3600 lbs per unit. While I would be comfortable in putting 1200 lbs per unit, there is no way that I would try to put anywhere near 3600 lbs on these thing. These are just OK for home use. 3 - If you want to move these from one house to another (Maybe even from one room to another), plan on taking them completely apart. Because of their design, they tend to fall apart if they are not kept perfectly flat and stable. Again, an extra dollar in hardware would have solved this problem.

It lives up to the description: deep shelves, heavy duty. My only complaint is the assembly. The unit is split into two sections, upper and lower shelves so you can have it as one tall shelving unit, or two connected shelves side by side. Unfortunately, it is impossible for one person to assemble it into the one shelving unit. This is because you have to assemble the whole upper unit frame THEN put it on top of the lower shelves which stand 4 feet above the ground. Even if I was that coordinated or had help, the connectors were pretty loose on the upper unit (they don't click in securely and stay there), which means it looked like an Abbot & Costello routine to tring to move the frame around...one side popped out, then when it was in place the other side popped out...you get the picture. Maybe with a helper (or two) and if I temporarily taped all the connections together so they wouldn't keep popping out, we could lift it up and connect the upper and lower shelves. Instead, I am keeping it as separate shelving units for now even though that configuration is not best for my space. If I were designing the thing, I would simply add long joint supports so you could assemble the upper unit one pole at a time and it would stay put while you put the other peices together. As of now, the only thing that keeps the upper and lower units connected is that they share a shelf. Even weighted down, this is not very secure for earthquake zones. I would have had to bracket the upper unit to the wall for safety. Long story short, great unit fo the money if you want to use it in side by side configuration. Requires handyman expertise to assemble it as one unit. Hope all this helps.

Nice shelfing for the money. Easy to assemble except for when stacking the units. The connections where they stack need improvement. I made it work by drilling holes and inserting sheet metal screws with washers for the top unit to rest on. Without this mod it was challenging to get the top sections to stay together. However once assembled I was a happy trooper.

Deserves zero stars; stay away from this one. You have been warned.

Flimy, boards are thin, and horrible when stacking. Safety issue

IMPOSSIBLE to put together-will be returning soon!!

This is my 15th and 16th set of shelves I have purchased. They seem flimsy going up but are sturdy when finished. I will buy more.

The shelving is great but I was missing a part and Sam’s Club has yet to call me back or send the part it was missing

Putting together was difficult. Hard to explain how but if you got one piece clicked in place, 2 other pieces would fall out of place.

DO NOT BUY!!! Bought 2 sets of these shelves at my local Sam's Club. Had two major problems with them: 1) These shelves are built in two sections, stacked one on top of the other. The shelf supports are installed to connect the two sections. As you can see in the photos, the corner pieces that stack on top of each other are VERY thin so there's no real support. The slightest bump would knock the upper section off, even with them being connected. This was too dangerous for me so I chose to keep the sections separate, making 2 short racks with 3 shelves each. Not what I wanted but at least it won't come crashing down. Note: one of the pictures from the website shows the supports as being tapered to make them more interlocking. That's not what I got. Don't know if it would have solved the problem, but I wouldn't take the chance. 2) In one of the sets I purchased, 4 of the 6 shelves were cut too short, both length and width. This makes them completely unusable as the shelves are too small to fit on their supports.
